WILLIAM E. MEYER,

OF NEW YORK, N. Y.

Letters Patent No. 114,459, dated May 2, 1871.

IMPROVEMENT in SAIL-HANKS.

The Schedule referred to in these Letters Patent and making part of thesame.

To an whom it may concern Be it known that I, WILLIAM E. MEYER, of thecity, county, and State of New York, have invented a new and usefulImprovement in Hanks for Sails; and I do hereby declare the following tobe a full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification, in whichdrawing- Figure 1 represents a sectional front view of thisinventionwhenthe parts are locked.-

Figure 2 is a similar view of the same, showing the parts detached.

Similar. letters indicate corresponding parts.

This invention relates to a hank which is provided with a detachablekey, which, when secured in the hank, forms the connection between thesame and the sail in such a manner that by detaching the keys from thehanks the sail can be readily taken off and replacedyby auotherwithoutbeing compelled to take the hanks off from the rope. When the key is tobe conuected to the hank it is locked in its position by a dog andspring catch, and the back of said dog is camshaped, so that when thespring catch is drawn back the strain of the sail on the key is enabledto throw the dog back, and the key is released.

In the drawing-- The letter A designates a hank, which is by preferencecast of malleable iron, or which may be made of any other suitablematerial.

In this bank is made a mortise, a, capable or receiving the key B, whichis provided with eyes I), to take the rope by means of which the sail issecured to said key.

The key is formed with a lateral projection or nose,

0, which catches in a corresponding recess in the mortise a, (see fig.1,) and after the same has been introduced iuthe mortise it is locked inits position by a dog, 0. This dog swings on a pivot, d, secured in thehank A, and it fits into a recess, e, provided in the side of the bank.

In the tip of said dog is a spring catch, f, and if the dog is turned upthis spring catch looks into a cavity in the hank.

The back g of the dog is cam-shaped, so that when the key is in itsplace and said dog is turned up to the position shown in fig. 1, it willlock the key firmly in its position; but if. the spring catch is drawnback the strain of the sail acting on the key-will throw the dog down tothe position shown'in fig. 2, and the key is released,

.In order to efl'ect this purpose the pivot dot the dog must be situatedsomewhat below the lowest cor- .ner of the cam-shaped back, and the noseof the key must be 'inclinedat its .under side more or less, so

that a downward strain on. the key will be capableofturning the dog downto the position shown in fig. 2 as soon as the spring catch is opened.

,This bank is intended particularly for jib-sails on yachts, and bymeans of the detachable key I am enabled to take down the jib andreplace it by another in a very short time.

My hank may, however, be used with advantage for fore-and-aft sails andgaif-topsails, and it is obvious that its construction may be modifiedin various ways involving the same principle;

What I claim as new, and desire to'secure by Letters Patent, i s- 1. Ahank with a detachable key, constructed s-ub stantially in the mannerherein shown and described.

' 2. The dog 0 with its cam-shaped back 9, in combination with thedetachable key B and bank A, substantially as set forth.

This specification signed by methis 14th day-of February, 1871 W. E.MEYER.
